Abstract
Phosphorus (P) is an essential macronutrient for plant growth and development. To adapt to low inorganic-phosphate (Pi) environments, plants have evolved complex mechanisms and pathways that regulate the acquisition and remobilization of Pi and maintain P homeostasis. These mechanisms are regulated by complex gene regulatory networks through the functions of Pi transporters (PTs) and Pi starvation-induced (PSI) genes. This review summarizes recent progress in determining the molecular regulatory mechanisms of phosphate transporters and the Pi signaling network in the dicot Arabidopsis (Arabidopsis thaliana) and the monocot rice (Oryza sativa L.). Recent advances in this field provide a reference for understanding plant Pi signaling and specific mechanisms that mediate plant adaptation to environments with limited Pi availability. We propose potential biotechnological applications of known genes to develop plant cultivars with improved Pi uptake and use efficiency.
